HEINRICH GAENSSLEN AND GOTTHILF GAENSSLEN, OF ESSLINGEN,

ROTARY JEWEL.

SPECIFICATION forming part of Letters Patent No. 340,108, dated April 20, 1886.

Serial No. 172,627'i (No model.)

To @ZZ whom it may concern:

Beit known that we, HEINRICH GnENssLEN and GOTTHILF G AENssLnN, both citizens of Germany, residing at Esslingen, in the Kingdom of \Vrtemberg, Germany, have invented certain new and useful Improvements in Rotary Jewels, of which the following is a specilication.

Our invention relates to rotary jewels, adapted for oravats and similar articles of wearing-apparel.

Our invention consists of ornaments mounted on the main arbor of a watch mechanism, similar tothe hands of a dial thereof, whereby one ornament may be made to rotate in one direction,while the other rotates in direct opposition thereto, thus presenting a very beautiful optical illusion.

In the accompanying drawings, Figure l represents a cravat upon which are shown two Stars which are driven by watch mechanism held within the frame shown by dotted lines. Fig. 2 is a side elevation of the frame, showing the mechanism connected therewith. Fig. 3 is a view of the front plate, which also shows the mechanism connected in part to the back plate. Fig. 4 shows the mechanism under the front plate.

Similar letters of reference indicate similar parts throughout the drawings, in whicha represents tlicbarrelwvheel, provided with a projected draw-pivot, Z,which of course carries a fly-wheel. The teeth of the barrelwheel a mesh into those of the spring-wheel b. On the arbor of the latter is mounted the wheel c. The teeth of the latter mesh into those of the springwheel d, mounted on the same arbor with that of e, the latter of which engages with the toothed wheel mounted on the arbor car! rying the escapement wheel g, which is in junction with the escapenient, bei ng located in the space R.

Instead of using any escapement, some other wheels which end with a ily or balance wheel may be used, in order to effect a noiseless action.

In Fig. et will be shown the mechanism located beneath the plate H. The wheel 7L is fixed on the prolonged portion of the arbor carrying the spring-wheel d, which meshes into both the toothed wheels i and m. On the pivot of the spring-Wheel m, which is prolonged outward and bearing upon a small bridge, o, is a casing-tube,which is the bed for the spring-wheel n', and over which is set the wheel n by means of a leading tube. On the arbor carrying the spring wheel i is to be found the fixed wheel lc, which meshes into wheel a. It will be observed that the front star, q, which is composed of eight points,will rotate to the right,whilc the rear star, s, composed of sixteen points, will rotate to the left.

In Fig. 5 is shown a modification. XV and X will be allowed to turn in two pivots, on

which is fixed the complement p by a pin, p. This pin extends to the eccentrico', which is fastened on the pivot m of the spring-wheelmr of Figs. 3 and 4. On this object W is placed a square pin, u, adapted to enter the casing t, which is tixed upon the cylinder. This arrangement allows the moving figure to be less dependent on the works, as if figures to be moved were put directly on the complement of the spring-wheel.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

l. In `jewelry, the combination consisting of the jewels mounted upon arbors, one within the other, the arbors adapted to be rotated in opposite directions by watch or clock mechanism.

2. In jewelry, the combination consisting of the barrel-wheel a, draw-pivot Z, spring-wheel b, wheel c, spring-Wheel d, Wheel c, escape ment-wheel g, plates H and o, wheel h,wheels im, bridge o, spring-wheel n, wheel n, ixed wheel le, and stars q and s, the whole forming a complete device, substantially as shown and described.

In testimony whereof we hereunto sign our names, in the presence of two subscribing witnesses, this 18th day of May, 1885.
